FILLER MECHANISM FOR FOUNTAIN PENS.

Application filed. December 22, 1922.

To all whom it may] concern.'

Be it known that I. PAUL S. HAU'roN, a citizen of the United States, residing in the city of Newark, county of Essex. and State of New Jersey, have invented a certain new and useful Improvei'nent in Filler Mechanism for Fountain Pens, of which the following is a specification, reference being had to the accompanying drawings, which form a part of the same.

An object of my invention is toprovide fountain pen filler mechanism operable from the end of a fountain pen opposite to the nib, which may be controlled by turning the same with reference to the barrel of the fountain pen.

Another object of my invention is to positively limit the movement of the filler means.

Another object of my invention is to so construct my filler mechanism as to make it readily removable from a fountain pen for any desirable purpose.

Another object of my invention is the construction of a filler mechanism which may be completely assembled before insertion in the barrel of the fountain pen.

Other objects will be apparent upon reading this specification7 taken in connection with the accompanying drawings7 in which- Fig. 1 is a longitudinal cross-section ofa fountain pen embodying my invention, the ink-bag being shown in normal position;

Fig. 2 is a similar view of a fountain pen with the ink-bag in depressed condition;

Fig. 3 is a cross-section of the presser bar and controlling means;

Fig. 4 is a perspective view of the presser bar support; v

Fig. 5 is a cross-section of the filler operaing end of the pen with the screw sliding control for the presser bar.

Fig. 6 shows a form of hinge connection between the presser bar arm and presser bar.

Referring now in detail to the drawings: 6 represents a fountain en barrel, 7 a pen nib and 8 the ink-bag. t the ller 0perating end of the pen, I have provided a turnable button 9 in which is mounted to move integrally therewith the screw 10 having the core 11 and the screw head 12. Adapted to cooperate with the screw 10 and the threaded head 12 is a plug' 13 provided with a female thread 15 and having a slot 141. This plug is provided with apertures 16 in register with each other and which are adapted to support serial No. $08,542.

a pin 17 in which is swivelly mounted the presser bar operating lever 18 through the aperture 19 therein. On the presser bar operating lever 18 are two flanges 20,- only one of which is shown, having the cam surfaces 21 and 22 which lit in the recess 111 of the plug and over the core 11 and between the screw k10 and the head 12. At the desired point the presser bar 25v is connected by a swivelled joint 24 with the presser bar operating lever 18. Y

The turnable button 9 is provided with a recess 26 adapted to cover a portion of the plug 13, said recess having a shoulder 25 which acts as a. stop against the plug 13 in its movement toward the same. The part of plug 13 which enters the barrel V6 is preferably provided with serrated surfaces 27 adapted to be held by frictional Contact in said barrel, and thereby hold the plug 13 in rigid position relative to the turnable button 9.

In operation the filler operating machanism is assembled so that the turnable button 9, screw 107 core 11. screw head 12, plug 13, presser bar operating lever 18 and presser bar 23 constitute one unit, which is adapted to be inserted into the end of a fountain pen barrel in the same manner as a cork is pressed into the mouth of a bottle, the serrated surface 26 of the plug acting to hold the plug in stationary position in the barrel 6. The turnable button 9 is of slightly greater circumference than the rear end of plug 13 which is adapted to fit into said turnable button in a loose enough manner to permit the button to be turned without appreciable friction on the plug. 1f it is desired to fill the ink-bag 8, the button 9 is turned to cause it and the screw 10 to move away from the stationary plug 13 till the head 12 comes in Contact with the cam sur faces 21 of the lianges 20. Further movement of the screw 10 and head 12 connected therewith, will cause the operating lever 18 to swivel around the pin 17 till the cam surface 22 of the iange 2O touches the inner end of the slot 14. The presser bar 23 has now completely deiated the ink-bag 8 and further depressing movement of the filling mechanism is stopped by the Contact of the fianves 20 withthe end of slot 14: in plug! 13. 'he ink-bag now being in collapsed condition the' opposite end of the' pen is then inserted into an ink well and the botten 9 is turned in theop'poste vdirectiontillithe" screw 10 contacts with the'lc'a'm surfaces'QQ,thereby raising the presser bar 23 and permitting the button 9, which shoulder'acts'as astopfy I have described what I believe to beI the best embodiment'ofmy invention.
